Product Description

1. Product Overview

This is a high-precision injection mold specially designed for manufacturing medical-grade antibacterial nebulizing tube components. Built with 718H mold steel and optimized for medical-grade PP with 0.3% antibacterial additives, this mold delivers consistent, hygienic, and dimensionally stable plastic parts for respiratory therapy devices. It features a precision threaded interface molding design, ensuring leak-proof connections and meeting the strict hygiene requirements of the medical industry.

2. Core Features

✅ Medical-Grade Material Compatibility

Engineered for medical-grade PP with 0.3% antibacterial additives, the mold’s cavity surface is polished to medical-grade standards to avoid residue buildup and ensure the antibacterial properties of the material remain intact after molding.

✅ 718H Steel Construction for Medical Applications

Using premium 718H pre-hardened mold steel (28-32 HRC), the mold offers excellent wear resistance, dimensional stability, and corrosion resistance. It supports repeated EO sterilization cycles of the molded parts without mold degradation, ensuring long-term production consistency.

✅ Precision Threaded Interface Molding

The mold is equipped with a high-precision rotational unscrewing mechanism for the threaded connector section, ensuring thread pitch accuracy ≤ ±0.02 mm. This eliminates visible parting lines on the thread surface, guaranteeing airtight, leak-proof connections between the nebulizing tube and device.

✅ Cleanroom-Quality Mold Surface Treatment

All mold cavities are polished to Ra ≤ 0.4 μm to meet medical-grade cleanliness requirements. The smooth inner surface prevents bacterial adhesion, reduces drug residue on molded parts, and supports easy cleaning and sterilization.

✅ High-Cavity Efficiency for Mass Production

Available in multi-cavity configurations (customizable 2/4/8 cavities), the mold is optimized for short cycle times while maintaining consistent part quality. The balanced runner system ensures uniform melt flow, preventing material degradation and preserving the antibacterial additive efficacy.

✅ Strict Tolerance Control for Medical Parts

All critical dimensions (thread diameter, wall thickness, connector fit) are controlled to ±0.03 mm tolerance. The mold undergoes rigorous dimensional inspection to ensure every nebulizing tube component meets ISO 13485 medical device standards.

FAQ

Q1: Can this mold process other medical-grade plastics besides antibacterial PP?

A1: Yes, it can be adjusted to process medical-grade PE, EVA, and TPE materials, with minor modifications to the runner and cooling system.

Q2: How does the mold ensure the antibacterial properties of the material are not affected?

A2: The mold is designed with a low-shear runner system and controlled melt flow path to avoid overheating the material, which preserves the activity of the antibacterial additive.

Q3: What is the lead time for this mold?

A3: Standard lead time is 4-6 weeks for 2/4 cavity molds, with expedited options available for urgent orders.

Q4: Can the mold be modified for different thread specifications?

A4: Yes, we offer customization for different thread pitches, diameters, and connection standards to match your nebulizer device requirements.
